Fantasy is a genre of fiction that uses magic and other supernatural phenomena as a primary element of plot, theme, or setting. Many works within the genre take place in fictional worlds where magic is common. Fantasy is generally distinguished from science fiction and horror by the expectation that it steers clear of (pseudo-)scientific and macabre themes, respectively, though there is a great deal of overlap between the three (which are subgenres of speculative fiction).

In popular culture, the genre of fantasy is dominated by its medievalist form, especially since the worldwide success of The Lord of the Rings books by J. R. R. Tolkien. In its broadest sense however, fantasy comprises works by many writers, artists, filmmakers, and musicians, from ancient myths and legends to many recent works embraced by a wide audience today.

Fantasy is a vibrant area of academic study in a number of disciplines (English, cultural studies, comparative literature, history, medieval studies). Work in this area ranges widely, from the structuralist theory of Tzvetan Todorov, which emphasizes the fantastic as a liminal space, to work on the connections (political, historical, literary) between medievalism and popular culture

The feeling of trust, kindness, and friendship between a group of high school students for example, is a central theme of this anime.

Friendship

Romance describes a story that deals with love between two or more characters typically also having an optimistic ending. Romance is also a difficulty encountered when creating a harem.

Since a large part of the anime audience still takes part in school life or is visiting college, it is only natural to choose a setting the audience can identify with, be it elementary, middle, or high school. For the older viewers a college setting with more mature real-life problems is appropriate. And since clubs take up so much time in the lives of students, these are obviously also important.
